Phototrophic microorganisms (microbial phototrophs) use light as an energy source to carry out various metabolic processes producing biomaterials and bioenergy and supporting their own growth. Among them, microalgae and cyanobacteria have been utilized extensively for bioenergy, biomaterials, and environmental applications.
A National Renewable Energy Laboratory (NREL) study projects that solar and wind generation combined would approach 70% by 2035, in a lowest-cost grid.
Inflation Reduction Act (IRA) incentives will drive an increased pace of renewable deployment, NREL projects, as shown by the black line at the top of the nearby image. Other lines in the image show NREL’s projections from prior years, when there were no IRA incentives.
The last time a sitting president visited an ethanol plant was to announce the availability of year-round E15 by then President Donald Trump. With President Joe Biden’s visit to an Iowa ethanol plant on April 12, he too offered a path forward for year-round E15 use after Trump’s attempt was previously struck down by the courts.
On December 1, 2022, EPA announces a proposed rule to establish required Renewable Fuel Standard (RFS) volumes and percentage standards for 2023, 2024, and 2025, as well as to propose a series of important modifications to strengthen and expand the RFS program.
Solar, wind and other renewable energy sources are expected to continue building momentum, increasing installed capacity by 75% through 2027, said the International Energy Agency (IEA). The growth in deployment would represent as much capacity added in the next five years as the last 20, adding about 2,400 GW over the period.
The U.S. Department of Energy announced Tuesday a monumental milestone in nuclear fusion research: a "net energy gain" was achieved for the first time in history by scientists from the Lawrence Livermore National Laboratory in California.
"Simply put, this is one of the most impressive scientific feats of the 21st century," Jennifer Granholm, U.S. energy secretary, said at a press conference, adding that researchers have been working on this for decades.
How’d you like to eliminate your propane grain drying bill while opting for a green option at a fraction of the cost?
Mike Milligan, who farms about 4,500 acres with his father, Dave, in Michigan’s Cass City, is the first in the U.S. to install a Triple Green Products biomass heating system, and he’s put it to the test this past harvest.
Meet the climate entrepreneurs building solutions to future-proof Earth.
Last week a bipartisan group of senators introduced a bill that would make blends of ethanol up to 15% available year-round. The move was to create a federal standard for the higher use of ethanol versus letting each state make a move, which was worrisome to the petroleum industry.
Earlier the American Petroleum Industry joined ag-friendly voices to support such a member, a first for an organization that has not always been a friend of ethanol. The specter of state-by-state rules regarding ethanol blending is a potent incentive for federal action.
The Environmental Protection Agency today released the proposed Renewable Fuels Standard “Set” rule, which increases the amount of ethanol and biofuels oil refiners must blend into fuel for the next three years. The announcement also includes series of important modifications to strengthen and expand the RFS program.
The agency's long-awaited proposal outlines overall blending mandates of 20.82 billion gallons in 2023, 21.87 billion gallons in 2024, and 22.68 billion gallons in 2025.
